TURF-CUTTING ATTACHMENT FOR PLOWS.

SPECIFICATION forming part of Letters Patent N0. 767,714, dated August16, 1904:.

Application filed June 22, 1903. Serial No. 162,665- (No modelfl '10 allwhmn it may concern:

Be it known that I, FRANK RnNFRow, a citizen of the United States,residing at Redmondville, in the county of Yazoo and State ofMississippi, have invented a new and useful Turf- Cutting Attachment forPlows, of which the following is a specification.

This invention relates to colters or cutters for plows of that classwhich are adapted to be connected with the landside of the point of anyplow of ordinary construction, its purpose being to cut through the turfor soil, so as to facilitate the turning of the furrow-slice.

The object of my invention is to provide a device of this class whichshall possess superior advantages in point of simplicity, dura bility,and general efliciency and by the use of which a plow equipped with myinvention shall avoid being clogged by grass, roots, weeds. or otherobstructions.

My invention therefore consists, essentially, in the peculiar shape ofthe colter or cutter which is to be hereinafter described, whereby aplow equipped therewith shall be practically self-cleaning, as will behereinafter fully described, and particularly pointed out in the claim.

In the accompanying drawings, Figure 1 is a perspective view of aplow-point equipped with my improved colter or turf-cutter. Fig. 2 is aside elevation of the same seen from the landside. Fig. 3 is a detailview of the colter or turf-cutter detached.

Corresponding parts in the several figures are indicated by similarnumerals of reference.

1 designates a plow-point of any suitable construction, said pointhaving the share 2 and the landside 3.

4 designates my improved colter or turfcutting attachment, whichconsists of an elongated blade having a cutting edge 5 extending fromthe lower to the upper extremity of its front side, said cutting edgebeing parallel to the back 5 of the blade. Said cuttingblade is providedat its lower end with an angular foot 6, the lower edge of which isdisposed at an angle of about forty-five degrees to the front cuttingedge. The foot 6 is provided with perforations 7 for the reception ofrivets 8, by means of which it is in practice secured 5 to the landsideof the point. When thus secured, it will be observed that the cuttingedge of the device slopes back at an angle of about forty-five degreesto the surface of the soil, the slope of the upper edge of the landsidebeing considerably less say about twenty degrees. The cutting edge ofthe colter will thus be disposed at an angle of about one hundred andfifty-five degrees to the surface of the soil or the lower edge of thelandside. 6

Thus when the colter or cutter encounters the turf it will engage thelatter with a long sloping cut, which is eflicient in severing the rootsof the weeds and plants encountered and which,

furthermore, offers no obstruction that might 5 possibly cause theclogging of the implement by becoming entangled with such obstructions.It will also be noticed that the under or rear edge of the cutter 4 isdisposed directly adjacent to and in engagement with the 7 over the rearedge of the plow-point, there being absolutely no place where roots orthe like may hang or stick.

My improved colter or turf-cutting attachment is extremely simple inconstruction and inexpensive, and it may at a trifling cost be 5attached to the point of almost any plow now in general use.

By the construction herein described it will be noticed that anextremely slender blade may be used, the triangular foot at the lower 9end of said blade serving for the attachment of the device, while theportion of the blade which constitutes the cutter is narrow and slender.The attachment may be made to fit various sizes of plow-points, theproportions being in each case so arranged that the angle By theconstruction shown 7 5 11 between the heel of the foot-piece and thebackof the blade shall coincide with the upper or rear edge of theplow-point.

Having thus described my invention, I claim- A turf-cutting attachmentadapted to be rigidly secured to the landside of a plow, the saidattachment including an approximately triangular foot and a slendercutting-blade, the cutting edge of Which forms an upward and rearwardcontinuation of the front side of the foot, the back of said blade beingparallel to the cutting edge and disposed at an angle to the heel of thetriangular foot, said angle coinciding With the upper rear edge of theplowpoint to which the device is attached.

In testimony that I claim the foregoing as my own I have hereto aflixedmy signature in the presence of two Witnesses.

FRANK RENFROVV.
